5162 Exam Domains 2026: Complete Guide to All 3 Content Areas

Exam Overview: What You're Actually Facing

Praxis Algebra I (5162) is developed and administered by Educational Testing Service (ETS), delivered either at an ETS-affiliated test center - including Prometric locations and university testing sites - or at home through online proctoring. The exam consists of 60 questions total, a number that includes both scored items and unscored pretest questions ETS uses to field-test future material. Because of this blend, the exact count of questions you see within any single content area can shift slightly from one test form to the next, even though the percentage weights stay consistent.

You get 150 minutes to complete the entire test, and it's fully computer delivered. There's no essay, no separate calculator you bring from home - ETS provides an on-screen graphing calculator throughout, which changes how you should think about preparation. Rather than practicing calculator mechanics, your energy is better spent on interpreting what a problem is asking and choosing the right algebraic approach.

Content is organized into three domains, and understanding how each one is defined - not just its percentage - is the difference between generic review and targeted preparation. For a broader walkthrough of pacing and preparation strategy, see the 5162 Study Guide 2026, and if you want a distilled one-page reference while you study, the 5162 Cheat Sheet is built for quick review sessions.

Domain 1: Principles of Algebra (38%)

Principles of Algebra is by far the heaviest domain on the 5162, representing 38% of the test - roughly 23 of the 60 total questions. If you only had time to master one domain deeply, this is the one, because it touches nearly every other skill tested elsewhere on the exam.

Because this domain rewards conceptual justification as much as procedural accuracy, expect items that present a partially completed solution and ask you to identify the property or reasoning that supports the next step. This "justify the step" format is a recurring signature of the 5162 and is worth practicing explicitly, not just solving problems start to finish.

Domain 2: Functions (30%)

Functions make up 30% of the exam and build directly on the algebraic manipulation skills from Domain 1. Where Principles of Algebra asks you to solve and justify, Functions asks you to interpret relationships - how variables behave, how graphs represent those behaviors, and how different function families compare.

Because the on-screen graphing calculator is available the entire time, Functions items often reward candidates who know how to use graphing as a verification tool - sketch or graph a function to confirm an algebraic answer rather than relying on computation alone. This domain connects tightly with average rate of change and slope from Domain 1, so reviewing them together, rather than in isolated silos, tends to be more efficient.

Domain 3: Number and Quantity; Probability and Statistics (32%)

The third domain combines two related strands - Number and Quantity, and Probability and Statistics - into a single content area worth 32% of the test. This combined weighting means it's nearly as significant as Functions, and candidates sometimes underestimate it because it doesn't sound as "algebra-heavy" as the other two domains.

This domain draws directly from the NCTM Principles and Standards for School Mathematics (2000) and NCTM CAEP Standards (2020), which shape the exam's overall framework rather than any single state's curriculum. That's an important distinction: the 5162 is not written to match one state's math standards, so don't assume your local curriculum covers every topic ETS expects - this is worth reading closely in the 5162 Requirements guide before you register.

Question Formats You'll See on Screen

One of the more distinctive features of the 5162 is its format variety. This isn't a test of plain multiple-choice questions - ETS uses a mix of interaction types designed to test reasoning in different ways.

• Selected-response: select one answer, or select one or more answers
• Numeric-entry and fraction-entry: type in an exact value rather than choosing from options
• Drag-and-drop: arrange terms, steps, or values into correct positions
• Table-grid items: complete or interpret information organized in a grid
• Text-completion: fill in missing pieces of a mathematical statement or proof
• Select-an-area: click a specific region of a graph or figure to answer

This variety means memorizing answer patterns won't help - each format demands you actually produce or identify a correct mathematical object, not just recognize a similar-looking distractor. If you've only practiced with plain multiple-choice questions, you'll want to specifically rehearse numeric-entry and drag-and-drop formats before test day, since the interaction itself can slow you down if it's unfamiliar.

Turning Domain Weights Into a Study Plan

Generic study advice tends to treat all content equally, but the 5162's domain weights make that inefficient. With Principles of Algebra at 38%, Number and Quantity; Probability and Statistics at 32%, and Functions at 30%, your review time should roughly mirror that order of priority - while still covering all three, since the gap between domains isn't extreme.

This sequencing front-loads the highest-weight domain while leaving format familiarity for closer to test day, when the mechanics of numeric-entry and drag-and-drop items are freshest in your mind.

Who Actually Takes This Test

There's no formal prerequisite to register for the 5162, though most examinees have completed a bachelor's degree program with an emphasis in mathematics or mathematics education. The test is commonly used to satisfy requirements for an Algebra I add-on endorsement, meaning many candidates are already licensed teachers expanding what they're authorized to teach, rather than first-time entrants to the profession.

Registration runs through ETS at a flat $130 fee - there's no tiered pricing based on membership or state, which simplifies budgeting compared to some other credentialing exams. Your registration includes four free score recipients, so you can send results directly to the certifying agencies or institutions that need them without extra cost. If you don't pass on your first attempt, you can retake the test after a 28-day waiting period, and scores remain reportable for 10 years, giving you flexibility in timing your certification paperwork. A complete fee breakdown, including what happens with retakes, is available in the 5162 Certification Cost guide.

Because content aligns with NCTM standards rather than a specific state framework, this test travels reasonably well across states that accept it for Algebra I endorsement purposes - though you still need to confirm your specific state's passing score, which is covered separately in the Passing Score guide. If you're weighing whether this credential fits your career plans at all, Is the 5162 Certification Worth It? walks through the decision from a few different angles, and 5162 Jobs outlines the kinds of teaching roles this endorsement typically supports.

Before you lock in a test date, it also helps to review scheduling windows and blackout considerations in the 5162 Exam Dates article, and to run a few timed sections using practice questions on our practice test platform so you know how the 150-minute limit actually feels against real content.
